摘　　要：北京地区地裂缝成因复杂,是平原区主要地质灾害。本文总结北京地区地裂缝的勘查方法,提出了地裂缝勘查评价体系。对地裂缝现状、预测和综合评价方法进行了探讨,认为地裂缝现状危险性评价应以活动强度为主要指标,预测地裂缝潜在危险是评价的重点。建议将地裂缝成因及工程建设类型等纳入评价指标体系。The ground fissures are one of the main geological disasters in Beijing area and have complex origin. This paper summarized the exploration methods and put forward the prospecting evaluation system of the ground fissures in Beijing. According to current situation of ground fissures, forecasting and comprehensive evaluation methods have been discussed. That activity intensity is the main index of ground fissure risk assessment, and ground fissure potential risk prediction is the focus of evaluation. So this article proposed to the cause of ground fissure and the type of project construction into the evaluation index system.
